Subject: [PATCH net-next 1/3] dt-bindings: net: add new properties for of_get_mac_address from nvmem

From: Fugang Duan <fugang.duan@....com>

Currently, of_get_mac_address supports NVMEM, some platforms
MAC address that read from NVMEM efuse requires to swap bytes
order, so add new property "nvmem_macaddr_swap" to specify the
behavior. If the MAC address is valid from NVMEM, add new property
"nvmem-mac-address" in ethernet node.

Update these two properties in the binding documentation.
